While it's true that you may not understand the inner workings of many of the everyday objects we take for granted, it would be inaccurate to say that you don't know how anything works. While it may not be necessary to know the exact mechanisms of how an object works in order to use it, having an appreciation of the science behind these objects is essential to truly understand how they work.
Take the example of a mirror. While you may not understand the physics of how light is reflected, you likely understand the concept of reflection. Reflection is a phenomenon that occurs when light or another form of energy hits a surface, bounces off of it, and is redirected in a different direction. This same principle is used in many everyday objects, from a mirror to a radio antenna.
Similarly, you may not understand the exact science behind how a fan works, but it is likely that you understand the concept of airflow. Airflow is simply the movement of air from one place to another. Understanding this concept is essential to understanding how a fan works. The fan blades move air, creating a cool breeze, which is especially useful on a hot day.
Although it is true that you may not know the exact mechanisms of how an object works, it is still possible to have an appreciation of the science behind these objects. This appreciation is essential to truly understand how everyday objects work. By understanding the basic principles of reflection and airflow, you can gain a greater understanding of how mirrors, fans, and other everyday objects work.
